(5,65) (7,71) slope

Studentka2010 [4]

Answer:

Step-by-step explanation:

The slope formula is m=y2-y1/x2-x1

y2 is 71

y1 is 65

x2 is 7

x1 is 5

71-65 is 6

7-5 is 2

So the slope looks like this:

6/2

Simplify:

Which is 3

how much interest will roxanne have to pay if she borrows $3,000 for 3 years at a simple interest rate of 2%

Darya [45]

Simpe interest rate = PRT/100
— ( principal x rate x time ) / 100

$3,000 is the principal
3 years is the time
2% is the rate

so, PRT/100
(3,000 x 3 x 2) / 100
= $180

Answer : $180

5. Find the general solution to y'''-y''+4y'-4y = 0

CaHeK987 [17]

For any equation,

$a_ny^(n)+\dots+a_1y'+a_0y=0$

assume solution of a form, $e^{yt}$

Which leads to,

$(e^{yt})'''-(e^{yt})''+4(e^{yt})'-4e^{yt}=0$

Simplify to,

$e^{yt}(y^3-y^2+4y-4)=0$

Then find solutions,

$\underline{y_1=1}, \underline{y_2=2i}, \underline{y_3=-2i}$

For non repeated real root y, we have a form of,

$y_1=c_1e^t$

Following up,

For two non repeated complex roots $y_2\neq y_3$ where,

$y_2=a+bi$

and,

$y_3=a-bi$

the general solution has a form of,

$y=e^{at}(c_2\cos(bt)+c_3\sin(bt))$

Or in this case,

$y=e^0(c_2\cos(2t)+c_3\sin(2t))$

Now we just refine and get,

$\boxed{y=c_1e^t+c_2\cos(2t)+c_3\sin(2t)}$

Hope this helps.
